Produce an un-normalized psd based on an fft and a vector of optimal sine tapers
1 2 | resample_fft_rcpp(fftz, tapers, verbose = TRUE, dbl = TRUE,
tapcap = 1000L)
|
fftz |
complex; a vector representing the dual-length |
tapers |
integer; a vector of tapers |
verbose |
logical; should messages be given? |
dbl |
logical; should the code assume |
tapcap |
integer; the maximum number of tapers which can be applied; note that the length is automatically limited by the length of the series. |
To produce a psd estimate with our adaptive spectrum estimation method, we need only make one
fft calculation initially and then
apply the weighting factors given by parabolic_weights_rcpp
, which this
function does.
1 2 3 | fftz <- complex(real=1:8, imaginary = 1:8)
taps <- 1:4
try(resample_fft_rcpp(fftz, taps))
